Donor–acceptor covalent organic framework hollow submicrospheres with a hierarchical pore structure for visible-light-driven H₂ evolution

Abstract

Two-dimensional (2D) covalent organic frameworks (COFs) have received much attention due to their tunable electronic structures and superior surface area in visible-light-driven water splitting. Compared to traditional photocatalysts, 2D COFs...

A thiazolo[5,4-d]thiazole functionalized covalent triazine framework showing superior photocatalytic activity for hydrogen production and dye degradation

“…However, its photocatalytic hydrogen production rate is only 7324 μmol h −1 g −1 , indicating that the introduction of the TzTz moiety into the CTF can fully realize its photocatalytic performance. 79…”

“…However, its photocatalytic hydrogen production rate is only 7324 mmol h À1 g À1 , indicating that the introduction of the TzTz moiety into the CTF can fully realize its photocatalytic performance. 79 To further conrm the higher visible light utilization capacity of CTF-NWU-1, we tested the photocatalytic hydrogen production performance of the two polymers under irradiation with wavelengths greater than 520 nm. The results show that the hydrogen evolution rate of CTF-NWU-1 is also higher than that of CTF-NWU-2 under the same experimental conditions (Fig.…”

Covalent Organic Frameworks: Recent Progress in Biomedical Applications

“…Since there are many excellent reviews on COF-based materials related to assembly strategies, ,− energy applications, , gas separation, catalytic reactions, , or other applications, − it is not necessary for us to summarize the types of COFs on the basis of different linkages and the abovementioned applications. Instead, this review focuses on the recent developments of COFs for various biomedical applications.…”

A Heterostructure Photoelectrode Based on Two-Dimensional Covalent Organic Framework Film Decorated TiO2 Nanotube Arrays for Enhanced Photoelectrochemical Hydrogen Generation

“…The precisely tailored 2D COFs provide a platform to illustrate the structure–property relationships during the hydrogen evolution reaction. Various strategies have been developed to enhance the light-harvesting rate and charge separation efficiencies, such as band-gap engineering [ 13 , 14 ], donor–acceptor system fabrication [ 15 , 16 , 17 , 18 ], and linkage construction [ 19 ]. Their high crystallinity further facilitates rapid charge diffusion, ensuring optimal charge percolation.…”
